This grant proposal is in the field of computer vision. Its primary focus is on developing new 3D immersion technologies, from the perspective of capturing reality accurately as well as visualization (large immersive projections, single virtual headset). The goals are simple. First, we intend to provide highly accurate, fast, and robust methods for capturing reality immersively (large field of view) and in 3D, without any constraint on the motion of camera or the scene observed. Second, we intend to provide highly efficient methods for large scale visualization of immersive 3D content (i.e. dome multi-projection, or other large surfaces), and for small scale visualization, such as virtual headsets (i.e. oculus rift).******3D Immersion is becoming more prevalent everyday, especially in the arts, entertainment, and video games. This is due mostly to recent advances in virtual headset technology such as the Oculus rift and to new interest toward 3D dome projection, where the screen is not only filling the observers fields of view, but also provides stereo images, so depth can be perceived accurately in all directions. Content creation for 3D immersion is mostly performed with 3D computer graphics, where it is easy to make stereo-immersive rendering. However, the accurate depiction of reality requires real world filming and has remained a challenge. Traditional "small field of view" stereo capture can not be used directly for immersion because it provides a single point of view while immersive capture requires capturing from all possible point of views simultaneously. The single person immersive 3D experience is also evolving rapidly in the form of new high performance virtual reality headsets. Software for viewing content has matured, especially with regards to 3D real-time graphics and video games. However, for immersive video, the large resolutions involved and geometry corrections (including parallax) still constitute a challenge. Our research program intends to explore 3D immersion, from the perspective of content creation and content presentation.******We will develop new cameras for 3D spherical capture of reality, so it can be observed somewhere else with accurate depth perception in any direction, and in real-time.******We will also develop better multi-projection, to simplify and automate its deployment while making it more perceptually accurate immersion with depth.***Our long term goal is the "ultimate immersive 3D" experience, where the observer not only controls his gaze, but also his location. This new freedom for the observer will have a profound impact on the creation of 3D immersive content and make it much more challenging, thereby opening new avenues of research. Overall, if this research program is successful, we will have contributed to achieving the ultimate goal of 3D immersion: giving full freedom of movement to the observer, giving him a true felling of omnipresence.

该赠款提案在计算机视觉领域。它的主要重点是从准确捕获现实以及可视化（大型沉浸式预测，单个虚拟耳机）的角度开发新的3D沉浸技术。目标很简单。首先，我们打算提供高度准确，快速且可靠的方法，以沉浸式（较大的视野）和3D捕获现实，而不会对相机运动或观察到的场景进行任何限制。其次，我们打算提供高度效率的方法，用于对沉浸式3D内容的大规模可视化（即圆顶多反射或其他大型表面）以及小型可视化（例如虚拟耳机（即Oculus Rift）。******* 3D浸入量变得更加普遍，尤其是在艺术中，尤其是艺术，娱乐，娱乐和视频游戏。这主要是由于诸如Oculus Rift等虚拟耳机技术的最新进展以及对3D圆顶投影的新兴趣，在屏幕上不仅填补了观察者的视野，而且还提供了立体声图像，因此可以在所有方向上准确地感知深度。 3D沉浸式的内容创建主要使用3D计算机图形，在该图形上很容易制作立体声渲染。但是，对现实的准确描绘需要真实的拍摄，并且仍然是一个挑战。传统的“小型视野”立体声捕获不能直接用于沉浸，因为它提供了一种观点，而沉浸式捕获需要同时从所有可能的观点捕获。单人身临其境的3D体验也以新的高性能虚拟现实耳机的形式迅速发展。查看内容的软件已经成熟，尤其是在3D实时图形和视频游戏方面。但是，对于沉浸式视频，涉及的大决议和几何校正（包括视差）仍然构成挑战。我们的研究计划打算从内容创建和内容呈现的角度探索3D沉浸式。深度。***我们的长期目标是“最终的身临其境的3D”经验，观察者不仅控制着他的目光，还控制着他的位置。观察者的这种新自由将对创建3D沉浸式内容产生深远的影响，并使其更具挑战性，从而开辟了新的研究途径。总体而言，如果这项研究计划成功，我们将为实现3D沉浸的最终目标做出贡献：向观察者提供全部运动自由，使他真正地无所不在。
